soil contamination monitoring Articles

In 1999 Italy’s Environmental Protection Agency (ANPA) published a paper on the methods to be used in the case of mosses and soils. After nearly a decade, a review is advisable. The attached Guidelines take account of numerous experiments in the environmental field and include a short description of bryophyte biology. A great many pollutants are present in our environment. In addition to ...

Remove Contaminated Soil from Residential Gardens & Re-Landscape Client: MTM Construction Consultant: WA Fairhurst and Partners Challenge: Advise on the removal of contaminated material from a residential area built on a former town gas site. Reinstate existing landscaping. Applied ...

From the beginning of World War II until the 1970s, the site that is now the Naval Surface Warfare Center in Crane, Indiana (NSWC-Crane) was the home of a major bomb manufacturing operation. Explosive compounds such as TNT, Royal Demolition Explosives (RDX) and Her Majesty’s Explosive (HMX) were handled loose and drifted through air vents. Often, the material settled on the roofs of buildings, ...

While Brazil has not changed its waste generator liability since adopting Law 6.938 in 1981, it has updated and altered requirements for generators. Most recently, the Brazilian National Council on the Environment (CONAMA) adopted CONAMA Resolution 420/2009, establishing guidelines and criteria for the management of contaminated sites. CONAMA Resolution provides for the creation of soil quality ...

SITE OWNER: A National Overnight Express Package Company SITE SURVEY: Site and geological surveys revealed a contaminated area north of the facility and west of a diesel tank pit. The cause of the contamination was the result of two (2) underground storage tanks (UST™). One tank contained waste oil while the other contained new oil. Both tanks had ...

An investigation and remediation of TNT contaminated soils and wastes was conducted at the Apache Powder Superfund Site in Cochise County, Arizona during 1999 and 2000. TNT contamination was most likely the result of salvage operations of World War I munitions. Characterized by a steep hillside and arroyo cutting through the wastes, the site offered challenges of stability, access, health and ...

Can an old drill site be cleaned up without adding truckloads of contaminated soil to the landfill? Chevron Canada will be using a technology called thermal desorption to clean up a site located 13 kilometres southwest of Pincher Creek. Leif Sollid, spokesman for Chevron, who is the operator of the site, said they considered two options for the clean up. The soil is classified as a non-dangerous ...

The effect of compost on hydrocarbon degradation was determined during a 120-d incubation period. An evaluation of soil basal respiration and dehydrogenase activity as a monitoring instrument for the bioremediation process of soil contaminated with commercial diesel-oil was carried out. Six soil samples were used: S (control, uncontaminated soil), CS (contaminated soil), CSS (contaminated and ...

In addition to plastic in the oceans, plastic contamination in arable land throughout Europe and other parts of the world is a growing problem. No standards exist for these types of soil pollutants, nor for pesticide residues or their degradation products. For this reason, Professor Violette Geissen is calling for standards to be implemented. On 15 June, Geissen will deliver her inaugural address ...

Project Highlights Over the last 15 years, Envirochem have for-filled the role of environmental consultant analysts to the University of Southampton. During a period of significant redevelopment, Envirochem has assisted with a whole range of projects supplying an exhaustive range of asbestos related services, chemical sampling and ...

In our experience, Bioremediation is best accomplished with Bio-augmentation, the addition of large numbers of selected micro-organisms grown in the production laboratory. In addition to bio-augmentation, several physical and chemical parameters must be controlled in order to obtain optimal growth and maximum degradation of soil contaminants. The major factors that are controlled during ...

ANA Shipyard is located on Elizabeth river and during additional construction work, it was discovered that the ground water was contaminated with free product due to soil contaminated with a mixture of oils and greases. Excavation of soil and replacement with clean dirt was not an option since it would contaminate the river. It was recommended by the Virginia DEQ that the cleanup should be done ...

Up until the early 1970s when The US Congress passed The Clean Water Act, industrial chemicals and petroleum products were routinely dumped onto the ground or poured down wells. In those days, few people understood groundwater hydrology, and disposing of chemical waste underground seemed like a safe and easy solution. Depending on the chemistry, underground pollution can linger for centuries, ...

Summary 1- Fontenay-Aux-Roses CEA Clean-up methodology For the denuclearisation of the first French nuclear research centre (CEA), the centre of Fontenay-aux-Roses started developing in 1999 a clean-up methodology to rehabilitate places that have been contaminated by radioactive materials. The structure of this methodology is comparable to the one that the ...

LOCATION: Tiverton, Rhode IslandPROJECT DATE: April, 1993 to PresentCLIENT: Confidential BACKGROUND: Soils at this 106 acre former petroleum product storage terminal have been impacted with gasoline, jet fuel, and diesel fuel over the course of 50 years. Estimates of the impacted soils range from 200,000 to 400,000 cubic yards. ACTION TAKEN: Ex-situ bioremediation is being used ...

The present study sought to identify Escherichia coli sources in a small catchment and to use the agro-hydrological model soil and water assessment tool (SWAT) to estimate their impact on river water quality. The innovative aspects of this research are to assess the hourly variations of fecal contamination and to take these variations into account in the model to provide a better evaluation of ...

Introduction Surface and subsurface soils have different characteristics in natural attenuation. Mobile contaminants in subsurface soils diffuse into soil vapor and aqueous phase and thus are relatively easily subject to natural subsurface processes that can attenuate these contaminants. Most high-molecular-weight (persistent) organic and many inorganic contaminants will be immobilized in the ...
